Sharing Instantiated Objects in Windows Forms Application - Part II

Question

Following is some C# code from a Windows Forms application.  As can be seen, a class called Array_Handler is defined along with an event handler called button1_Click.  The event handler instantiates an object (newobject) of class Array_Handler, then invokes 2 methods in that class (array_method1 and array_method2).

   class Array_Handler
   {
      private int[][] array1;
      private int[][] array2;
     
      // Constructor for class Array_Handler
      public Array_Handler()
      {
         array1 = new int[9][];
         // Create 9 columns for each row in array1
         for (int i = 0; i < 9; i++)
            array1[i] = new int[9];

         // Create 9 columns for each row in array2
         array2 = new int[9][];
         for (int i = 0; i < 9; i++)
            array2[i] = new int[9];
      }

      // Array_Handler Method 1
      public int array_method1( int row, int column )
      {
         return 1;
      }

      // Array_Handler Method 2
      public int array_method2(int row, int column)
      {
         return 1;
      }

   }  // End class Array_Handler


      private void button1_Click(object sender, EventArgs e)
      {

         int row_index = 0;
         int col_index = 0;
         int rtrn_value;
         Array_Handler newobject = new Array_Handler();
         rtrn_value = newobject.array_method1(row_index, col_index);
         rtrn_value = newobject.array_method2(row_index, col_index);

      }


My question is whether or not another event handler can manipulate the same instantiated object that was just created by button1_Click.  Generally, how can multiple event handlers share the same instance of an object?

Thanks,
